摘要
Indoxyl sulfate(IS),a protein-bound indole toxin,is currently a key research focus regarding uremic toxins and renal injury both in China and internationally.Studies have shown that IS can upregulate the expression of TGF-β1,TIMP-1,and pro-α1(I),induce the production of free radicals,decrease superoxide scavenging activity,and promote the apoptosis of renal tubular epithelial cells,thereby exacerbating renal damage.As metabolomics research progresses,IS is emerging as a potential new biomarker for kidney injury.This paper reviews the progress of research on the application of IS in kidney injury over the past decade,drawing on resources from databases such as the CNKI and PubMed.The aim is to provide insights that can aid in clinical individualized treatment,enhancing the safety and effectiveness of patient care.
硫酸吲哚酚(IS)是一种蛋白质结合型吲哚毒素,是现在国内外研究尿毒症毒素与肾损伤的主要物质。3-IS可以通过上调TGF-β1、TIMP-1、pro-α1(I)等表达,诱导自由基产生,降低超氧化物清除活性,诱导肾小管上皮细胞死亡使肾损伤程度加重。随着代谢组学研究的不断深入,IS可能成为一种新的肾脏生物标志物。本文通过检索中国知网、PubMed等数据库,对近十年国内外有关硫酸吲哚酚在肾损伤疾病中的应用研究进展进行综述,旨在为临床的个体化治疗提供帮助,提高患者用药的安全性和有效性。
